Even before its official release, the HTC EVO 4G has been rooted to run Android 2.2. Although, the details of the root are yet to be released, a video posted on the xda-developers forum confirms that it is possible to run a vanilla Android 2.2 on the EVO.

The HTC EVO will be launched on Sprint’s network on June 4. However, last week, it was given away to all Google I/O attendees. Given that a large section of the Google I/O attendees are developers, it’s no surprise that the EVO has already been rooted.

The EVO is a beast of a device with a 4.3-inch TFT touchscreen, 1 GHz Snapdragon processor and 512 MB RAM. It will be available for $199.99 with a two year contract and for $449.99 without any contract.
